Bedrest may heighten baroreflex sensitivity; hypothesis-generating for orthostatic intolerance in microgravity and prolonged recumbency, needs prospective confirmation.
Does simulated microgravity alter cardiopulmonary baroreflex control of forearm vascular resistance in healthy men?
Simulated microgravity via 7 days of head-down bedrest increases the sensitivity of cardiopulmonary baroreflex control of forearm vascular resistance, likely due in part to hypovolemia.
Convertino et al. (1994) studied this question.
